Cyanobacteria – a hidden threat
Almost everyone certainly met with the Cyanobacteria outbreak in ponds and natural pools; however, in recent years it is nothing unusual in water reservoirs used as drinking water sources as well, which causes a plenty of difficulties to water treatment plants. The problem is usually not the cyanobacteria themselves but rather the substances they produce […]
Polymer Rheology
Nowadays we meet polymers everywhere. If we exclude a small cave next to a water spring we find the presence of polymers literally in every household. Do you want to make thermal insulation, to distribute water or gas, to paint, do you have cosmetics in your bathroom, have you invested in electronics or computer equipment? […]
Microplastics in water
Recently, the presence of plastics in water environment has gained considerable attention. Not only plastic litter that is visible to the naked eye, but also smaller debris – recognized as microplastics – are of a great interest. Microplastics (MPs; plastic particles smaller than 5 mm) have been detected in different water bodies, i.e. oceans, seas […]
Fluid mechanics
With the transport of bulk materials in the form of a two-phase suspension (liquid-solid phase) we can meet in a number of industries - chemical, food, mining, energy and many others. In addition to closed pipe systems, which are usually hidden for ordinary citizens in industrial agglomerations, the two-phase flow is part of river systems […]
Nanoporous membranes
Membranes are separation barriers, which allow a selective passage of components of single-phase and multi-phase gaseous and liquid mixtures. Membranes under the usual name filters are used for purification of water or air, but they are as well an essential component of advanced technologies ensuring, for example, an operation of nuclear reactors or extracorporeal artificial […]
Science Fair 2018
The incredible fourth year of the Science Fair is behind us! Almost 25,000 visitors came to see unique exhibitions in three days. The stand of the Institute for Hydrodynamics was very popular and appreciated by the visitors. People could see on posters what processes water had to pass to get from the source to human […]
